ZOC-Resin cement slurry system
ZOC-Resin CEM resin cement slurry system is composed of ZOC-RS10L resin as the main functional material, water loss reducing agent, retarder, defoamer and other additives. It has the characteristics of anti-corrosion, anti channeling, toughening, strengthening and cementation, temperature and salt resistance, system stability and strong universality.ZOC-RS10L resin is a polymerizable resin monomer, which can form polymer resin in the alkaline environment of cement slurry, so as to reduce the permeability of cement paste, achieve the characteristics of anti-corrosion, anti channeling, toughening and strengthening. With different types of retarders, the temperature range is 4℃~220℃, suitable for high temperature and high pressure, corrosive gas cementing, casing cementing, liner cementing, etc.
Application
- Suitable for 4℃~ 220℃cementing construction.
-It can be used in high temperature, high pressure, corrosive gas and shallow gas wells.
-It can be used for offshore platform and land cementing construction.
-It can use seawater to prepare cement slurry.
- It can be used for cementing in gypsum salt layer.
Characteristics
- Strong control of water loss and free liquid capacity
-Excellent temperature and salt resistance
-Cement stone strength develops well
-Excellent anti-corrosion and anti channeling ability
-Simple composition and convenient use
-Strong anti-pollution ability
-It has strong universality and can be applied to a variety of strata
-Good channeling prevention effect
